mcpskills-cli

Generate Agent Skills from MCP server tools. Connects via Streamable HTTP, discovers tools, and outputs a skill with schema docs and a call script in the language of your choice.

Why bake MCP into skills?

Skills are easy to understand, static, edit, and most coding and non-coding agents are adopting them. Traditional MCPs load all tools into context and pollute the agent; token penalty is also costly because of loading every tool. This is why we transform MCP into skills: skills reduce token consumption because the agent does not load all skills into context—it only loads them when necessary.

But why do we even need MCP?

MCP is a standardized protocol for AI agents to communicate. Because of this, any system can easily adopt it and create the necessary tools specific to their needs.

Install

pip install mcpskills-cli
# or for development:
pip install -e .

Usage

mcpskills-cli --url <MCP_SERVER_URL> --token <TOKEN> [--name <NAME>] [--output <DIR>] [--script <LANG>] [--multi-skills]

Examples

# Generate single skill with all tools (default)
mcpskills-cli --url http://localhost:8027/mcp/abc123 --token mytoken --name my-db

# Generate separate skill for each tool
mcpskills-cli --url http://localhost:8027/mcp/abc123 --token mytoken --name my-db --multi-skills

# Generate with Python call script
mcpskills-cli --url http://localhost:8027/mcp/abc123 --token mytoken --name my-db --script python

# Generate with Node.js call script
mcpskills-cli --url http://localhost:8027/mcp/abc123 --token mytoken --name my-db --script node

Credentials

Stored in ~/.mcps/credentials (INI format, chmod 600). One section per server, updated automatically.

[my-db]
url = http://localhost:8027/mcp/abc123/
token = mytoken

Rotate tokens by editing the file directly; no need to regenerate skills.
